The myopectineal orifice of Fruchaud encompasses all weak areas through which groin hernias can occur. It is bounded superiorly by which structure?
- A The inguinal ligament
- B The arch of the transversus abdominis and internal oblique muscles ✓
- C The iliopubic tract
- D The Cooper's ligament (pectineal ligament)
Correct answer: B. The arch of the transversus abdominis and internal oblique muscles
Explanation
The myopectineal orifice of Fruchaud is a single continuous weak area in the groin through which all groin hernias (direct, indirect inguinal, and femoral) pass. It is bounded superiorly by the arching fibres of the transversus abdominis and internal oblique muscles, medially by the rectus muscle, laterally by the iliopsoas muscle, and inferiorly by the pectineal line (Cooper's ligament) and pubic bone. This concept is the anatomical basis for the laparoscopic preperitoneal mesh repair covering the entire orifice.
